INTERNATIONALCELLUGO'ITON PRODUCTS 60., OF CHIGAGO, ILLINOIS, A CORPO- RATION OF DELAWARE PAD-MAKING MACHINE Application filed January 18, 1984. Serial No. 887,012.

My invention relates to machines for making catamenial bandages and the like wherein a pad of soft filling material is enclosed in a wrapper of gauze or other suitable material.

The principal objects of my invention are to make and cover pads of this character rapidly and with very little labor or expense; to automatically cut and wrap the pad; to apply the wrapper so as to leave loose ends pro ecting beyond the ends of the pad; to provide means for satisfactoril cutting a comparativel thick la er of so t absorbent material; and in genera to provide a simple, dependable machine which operates practicall without attention except to renew the stoc from which the pads are made.

Fi 15 is a perspective view of the complete pad; and

Referring to the drawings, the reference numerals 1 and 2 indicate respectively the two end standards of the machine which have the plate 3 extending between and secured to the upper ends thereof. Pulleys or drums 4 and 5 are journaled respectively at the upper ends of the standards 1 and 2 and carry the belt 6, the ili pper length of which runs over the plate 3. 1e plate 3 is provided with an opening 7 therethrough adjacent one end to receive the upper portion of the pulley 4 so that the upper extremity of the pulley is substantially flush with the upper surface of the plate, and the other end of the plate 3 is notched as indicated at 8 to likewise accommodate the pulley 5. The belt 6, at the delivery end of the machine, asses over an idler 9, around an idler 10 and is looped around another idler 11, all of which are journaled in the standard 2, and the idler 11 has a belt pulley 12 secured to one end thereof and connected by the crossed belt 13 to a smaller pulley 14 on a stripper roll 15 which is journaled at the upper end of the standard 2. The folding of the belt around the idler 11 affords a substantial frictional engagement.

to insure a positive drive of the roll 15 which is driven in the same direction but at a faster surface speed than the belt 6 and serves to divert the strip of material, carried along by the belt, from the latter to a cutting device which will be presently explained.

For regulating the tension of the belt 6, the shaft 16 which carries the roll 4 is journaled in bearing blocks 17 which are mounted on screws 18 at the upper ends of the standard 1, so that by turning the screws 18 the bearing blocks 17 and roll 4 carried thereby are adjustable to and from the other roll 5.

The belt 6 serves to propel a strip of pad covering material such as a gauze, along the upper surface of the plate 3 from the roll 19 which is carried at the outer ends of the brackets 20 which project forwardly from the standard 1. For the purpose of permitting the roll 19 to turn freely, a pair of antifriction rollers 21 are journaled at the outer end of each bracket 20 and support the spindle or shaft 22 of the spool 23 upon which which is directly above the roll 4 andservcs to hold the gauze against the belt 6 as it runs over the to of the roll 4, and from this roll the strip 0 gauze is led past the mechanism which deposits a pad of filling material thereon, then through folding devices which fold the side portions of the gauze strip'over the pads thereon, and is then taken off the belt by the stripper roll 15 and fed through a cutter which severs the gauze at points midway between successive pads.

The roll 26 is journaled in the outer ends of a pair of arms 27 which are pivoted respectively to the opposite sides of the plate 3 near the end so that the roll acts by gravity to exert the desired pressure on the gauze. For adjusting andholding the roll -19 so as to feed the strip of gauze in proper alignment with the pad feeding and strip folding mechanisms, each of the brackets is provided with a laterally and upwardly extending arm 28 near the outer end (see Fig. 3), through which an adjusting screw 29 is threaded so as to engage againstthe end of the shaft 22,

a lock nut 30 being provided on each adjusting screw to hold the latter in the adjusted position.

A shoe 31 is arranged to -bear against the periphery of the roll 19 to impose a slight tension on the strip 24, and is carried at the outer end of an arm 32 which is fixed on a shaft 33 carried by bearings 34 at the inner ends of the brackets 20. These bearings are formed with threaded stems 35 which are insorted through apertures in the horizontal web 36" of the respective brackets, and ma be adjusted to various elevations by the loc nuts 36 which are-threaded thereon at opposite sides of the web 36. The shaft 33 has arms 37 at the opposite ends thereof and extending at opposite sides of said shaft, and upon these arms are mounted adjustable weights 38 which may be secured in various ositions of adjustment b the set screws 39. Vith this construction t e weights inay be adjusted to afford the desired pressure of the shoe 31 against the roll 19 and the two weights afford sufficient inertia to prevent the shoe 31 being thrown away from the surface of the roll 19 by irregularity in the surface of the latter.

Referring now to the mechanism for form ing the pads and depositing same on the strip 24 of gauze or other covering material, a feed table 40 is mounted on a pair of standards 41 and 42 at right angles to and somewhat above the plate 3 and has the inner end or an extension thereof projecting over the e supports plate 3, as a shown in Figs. 2 and 4, and the tab a roll 43 of soft fillin material which is confined on the table 40 etween guides 44 along the side edges of the table 40. The extreme inner end of the table 40 is carried by a bracket 45 which has a dependin plate portion 46 secured to the adjoining e go of the plate 3 as shown in Fig. 4, said bracket being rovided with side extensions 47 with depen in bearings in which a roll 48 is journaled, and the outer ends of these extensions 47 have a plate 49 secured thereto with the face thereof lying in avertical plane substantially coinciding with the near edge of the belt 6. At the outer endof the table 40 is a roll 50 which is journaled in adjustable bearings 51 carried by screws 52, mounted on the standards 41 for adjusting the roll 50 in the same manner as the roll 4 hereinbefore described. A belt 53 passes around the rolls 50 and 48 so that the upper length runs over the upper surface of the table 40 between the guides 44, while the lower length of the belt passes around a pair of idler rolls 54 on the standard .42, and is looped around a drum 55 which is also journals in the standards 42.

Mounted under the plate 3 is a frame 255 carrying the driving mechanism for the machine. This frame has the main driving shaft 56, journaled therein, upon which isfixed a sprocket 57 which is connected by the link belt 58 to any suitable source of power.;

A number of shafts 59, 60 and 61 are also journaled in the frame 255 in arallel relations to the main shaft 56, and t e shafts 56, 59 and 60 have the sprockets 61, 62 and 63 re- 0 sin 263 as indicated in Fig. 1, w ereby the shafts 59 and 60 are driven from the main shaft, and this chain extends upwardly around a sprocket 64 which is fixed on the shaft 16 for driving the roll 4 and belt 6. A

9 bell crank 65 is pivoted at the elbow, as indicated at 66, on a cross brace 67 of the frame 255, and has the outer end of the arm 68 7 thereof connected by the link 69 to the outer end of the arm 70 which is pivoted at its inner end on a shaft 71 which carries the drum 55. A pawl 72 is pivoted on the arm 70 and held by the s ring73 in engagement with a ratchet wheel 4 w 'ch is connected to rotate with the drum 55 so that the oscillation of the arm 70 serves to advance the drum 55 with a step by step movement. For rocking the bell crank 65, a cam disk 7 5 is secured on the shaft 60 and provided with a cam face 76 which cooperates with a roller 77 on the lower end of the arm 78 of the bell crank 65, said rollbr being held againstthe cam face by a spring 79 which .has' one and connected to thelarm 68 and the other and connected to the underside of the plate 3. The cam mechanism which I have just described, serves to intermittengfi operate the belt 53 to feed the strip 80 of ing material from the roll 43 to a cutter which severe the proper amount spectively fixed thereon and eng'a ed by the 1;794,sas

therefrom to form the filling pad. For the purpose of adjustment to permit proper engagement of the 'pawl 72 with the teeth of the ratchet wheel 74, the link 69 is preferably in the form of a turnbuckle, with eye members threaded on the ends so that the length of the link may be varied as required,

' vary the extent to which the strip 80 is advanced upon each 0 eration of the arm 68.

The roller 43 0 filling material is not mounted on the fixed axis but is mereiy confined between abutments 83 and 84, the former of which is secured to the outer end of the table 40 and the latter of which is secured to the guides 44 and bridges the strip of filling material and the belt 53 on the table 40.

For holding the strip 80 of filling material against the belt 50 adjacent the delivery end of the latter so as to insure a positive feed of the said strip, a pair of rolls and 86 is mounted in spaced relation on brackets 87 which are carried by the guides 44, and have a belt 88 passed therearound so that the lower length of the belt engages the upper surface of the strip 80 and holds the latter close against the belt 53. A pair of arms 89 which is pivoted on opposite ends respectively of the shaft 90, which carries the roll 85, have the roll 91 journaled in the outer ends thereof and resting on the upper length of the belt 88 to serve as a belt tightener.

'For operating the belt 88, there is a gear 92 fixed on the shaft 93, to which the idler roll 54 is attached, and this gear meshes with a gear 293 on a shaft 94 which is journaled in hangers 95, depending from the brackets 87, and this gear 293 meshes with a gear 294 which is fixed on the shaft to which the roll 85 is fixed. A similar gear 96 is secured l to the shaft97, to which the roll 86 is attached, and the gears 294 and 96 mesh with an intermediate gear 98 which is mounted on a shaft 99 journaled in intermediate bearings of the bracket 87.

Immediately beyond the location of the belt 88 is a cover plate 100 which is mounted on the uides 44 and extends over the strip 80 of lling material, for holding the latter down against the belt 53, said plate being provided with rounded edges as shown in Fig. 4 so that the filling material readily slides thereunder.

Mounted on the under side of the plate 3 are spaced brackets 101, each of which has a pair of depending bearings 102 in which a shaft 103 is mounted for axial sliding movement. A bracket 104 is secured on the outer end of each rod and projects upwardly and thereof so that the upper surface of the late is in the plane of the upper surface 0 the upper length of the belt 53, and this plate serves as a temporary support for the end of the strip 80 during the operation of severing the end portion from the strip. A pair of brackets 106 is secured to the outer edge of the plate 3 and extend upwardly and inwardly thereover with the brackets 104 interposed therebetween, and these brackets 106 have a block 107 secured to their inner ends just above the plate for stripping the severed pad 108 from the plate 105 when the latter is withdrawn from underneath the pad 108. A spring 109 surrounds each shaft 103 and is compressed between the outer hearing 102 and an adjustable collar 110 on the shaft 103 to normally hold the brackets 104 and plate 105 at the inward limit of movement thereof, as indicated in Fig. 4, and the inner ends of these shafts beyond the inner bearings 102 are connected to a cross head 111. A pivot lug 112 is formed in the cross head 111 midway between the shafts 103 and is connected by the link 113 to the upper end of a rocker arm 114 which is pivoted intermediate of its ends to a. cross member 115 by means of a pivot pin 116. The lower end of this rocker arm 114 has a friction roll 117 thereon which is held by the springs 109 against the side of the cam disk 118 which is fixed on the shaft 56, and has the raised cam 'edge 119 operating at the proper time to withdraw the plate 105 from under the severed pad 108. l

A pair of guide posts 120 is mounted on the base 121 ad acent the frame 255 and extend upwardly at opposite sides respectively of the table 40, and have the upper ends connected together by the brace 122. These posts serve as a guide for a vertically reciprocable cutter which is carried by a cross head 123 which has bearings at each end slidingly engaging the posts 120. A motor 124 is mounted on this cross head 123 and may be connected by means of flexible conductors 125 or otherwise to a source of current so as to operate continuously. A rotary cutter 126 is secured to the armature shaft of the motor 124 so that the inner face thereof barely clears the outer face of the plate 49, when the cutter is depressed, and said cutter comprises a thin disk with a knife edge which has been found particularly well adapted to make a clean cut through the soft filling material with which this machine is adapted to be used. A pair of spaced bearings 127 is formed on the cross head 123 at opposite sides respectively of the motor 124 to slidirigly receive the shafts 128; to the lower ends of which is secured a shoe 129. Each shaft 128 has a spring 130 thereon interposed between the bearing 127 and the shoe 129 for resilently holding the shoe in the lowermost position which is determined by collars 131 this connection,

which are adjustably secured on the upper ends of the shafts 128 above the bearings 127. This shoe 129 is of a suitable width to ex tend substantially from the outer edge of the guide 100 to the block 107, as shown in Fig. 4, and serves when the cross head 123 is depressed, to resiliently clamp the end portion of the strip 80 of filling material on the plate 105, the outer end of the belt 53 and adjacent portions of the framework over which the strip 80 passes, and this shoe has a slot 132 through which the cutter 126 is projected after the movement of the shoe 129 is interrupted by coming in contact with the upper surface of the strip 80. A

The cross head 123 is connected by a pair of parallel rods 133 to a lower cross head 134 which likewise slides on the posts 120 and is located underneath the table 40. This crosshead 134 is divided intermediate of the ends to receive the upper end of the link 135 therebetween which is pivoted on the pin 136,which latter has the ends engaged in the opposite sides of the divided portion of the cross head. The lower end of this link 135 is pivoted to the crank pin 137 of the crank 138 which is secured to the outer end of the shaft 61, which shaft is driven by means of the gear 139 which is fixed thereon and meshes with the gear 140 which is fixed on the shaft 60. By reason of the continuously driven cutter 126 and shoe 129 is reciprocated toand from the supported end of the strip 80, the parts bei so timed that the strip 80 is intermittent y advanced, being fed forward while the plate 105 is in the position shown in Fig. 4, whereupon the advance movement of the strip 80 is interrupted while the cutter is depressed to cut off a portion 108 from the end of the strip, after which the cutter and shoe are elevated and the plate 105 withdrawn to permit the severed pad 108 to drop down onto the continuously moving strip 24 of auze or other wrapping material. Immediately after the pad 108 is discharged as aforesaid, the plate 105 is returned to the position shown in Fig. 4 and the strip 80 advanced another step, whereupon the cutter again descends.

To facilitate the vertical reciprocation of the cutting mechanism, a cohnterweight 165 is provided therefor, which is carried by a chain 166 which is passed over an idler 167 and connected to a hook 168 on the lower cross head 134. The idler 167 is mounted on brackets 169 which are secured to the standard 42.

In order to insure proper deposit of the pad 108 onto the moving strip 24 of gauze or other covering material, it is desirable that the forward end of the pad should come in contact with the moving strip 24 before the rear end thereof comes in contact therewith, and to accomplish this result a plurality of inclined guides 141 are secured to a bracket 142 which is mounted at the rear end of the strip 107 so as to incline downwardly and forwardly under the rear end of the pad 108. These guides or fingers retard the dropping down of the rear end of the pad until the forward end thereof engages the moving strip 24 and is drawn forwardly thereby.

After the pads 108 are deposited 011 the strip 24, they are carried by said strip and the belt 6 between folding members 143 which are mounted on the plate 3 at opposite sides of the belt 6, and serve to fold up the side ortions of the strip 24 in the manner shown in Fig. 11, against the side edges of the pads 108. Beyond the folders 143 are successively arranged folder plates 144 and 145 positioned respectively at opposite sides of and extending over the belt 6 at a suitable elevation to first fold one side of the strip 24 over the pads 108 and then fold the other side thereover as shown in Figs. 9 and 11 to 14 inelusive, with the opposite sides of the strip 24 overlapped over the pads. A shoe 146 may, if desired, be pivoted on a bridge 147 over the belt 6 near the delivery ends of the folders 143 to prevent overthrow of the side portions of the strip 24 before the side portions reach the folders 144 and 145.

Mounted on the standards 2 at the delivery end of the machine is an inclined chute 148 which has the upper end positioned adj aeent the stripping roll 15 so that the latter delivers the folded strip 24 and enclosed pads onto this chute between the guides 149 which are secured to the side edges of the chute. This chute is pivoted near the upper end on a hanger 150 which has the ends secured to the standards 2, and the lower end of this chute is resiliently supported by one or more springs 151 which are seated in a block 152 carried by a bracket 153. This bracket has a \ledge 154 beyond the end of the chute 148 to which a shear blade 155 is adjustably secured by the cap screws 156. This shear blade extends across the end of the chute 148, and the cutting edge is normally below the outer surface of the chute 148 in the position in which the latter is normally held by the s rings 151, the parts being so arranged t at the folded strip 24 and pads therein readily pass off the end of the chute 148 yvsighout interference from the shear blade A pair of brfickets 157 is secured to the standards 2 and have a shaft 158 journaled thereon and the shaft is provided with a cutter head 159, to which a shear blade 160 is 10 and the sprocket is normally raised slightly above the cutting edge of the shear blade 155, it is necessary to depress the lower end of the chute at the time of the shearing operation, and to this end the cutter blade 160 is extended somewhat beyond the sides of the chute 148, and the guides 149 at their lower ends are beveled as indicated at 164, so that as the cutter 160 nears the cutting position, it engages the beveled edges 164 of the guides and depresses the lower end of the chute 148 sufficiently against the tension of the springs 151 so that the cutting ed es of the shear blades may cooperate.

e cutter 160 is rotated at a rate of speed corresponding to the rate of movement of the folded strip 24 so that as the cutter comes to the cuttin position, it neither retards nor pulls on t e strip, and moreover, the cutter 160 is disengaged from the lower end of the chute 148 as the shearing operation takes place, and thereby permits the immediate elevation of the lower end of thechute 148 so that the leading end of the folded strip 24 is readily advanced over beyond the cutter 155.

For conve ing the severed pads away from the lower en of the chute 148, I have provided a conveyer belt 170 which passes around a drum 171 on the standards 2 and over idlers 172 on a standard 173 so that the upper length of this belt passes under the lower end of the chute 148 in the direction indicated in Fig. 8. This conveyer and cutter 159 are both driven by a chain 174 which passes around and is driven by a sprocket 175 on the shaft 61, said chain being guided around the sprocket 176 on the cutter shaft 158 and the sprocket 177 on the shaft 178 of the drum 171 by an idler 179 on the shaft 180 which carries the drum 181 which is carried by adjustable brackets 182 on the standards 2. Adjusting screws 183 are provided in connection with the brackets 182 for regulating the tension of the driving chain 174.

In the operation of this machine, the pads 108 are deposited at regular intervals on the strip 24 of gauze so that a considerable length of gauze intervenes between successive pads so as to leave loose ends of the enclosing gauze on each pad as shown in Fig, 15. It is desirable to cut the gauze midway between the successive pads so that the loose ends 184 are of uniform length, and this necessitates the synchronizinglof the cutter 160 with the mechanism whic advances the strip 24 and particularly with the mechanism which severs and deposits the pads 108 onto the moving strip 24. In order that these mechanisms may be roperly synchronized, the upper and lower engths of the chain 174 are passed respectively under and over idler sprockets 185 and 186 which are adapted to be simultaneously raised or lowered to vary the time of the cutting operation of the cutter 160 with respect to the strip feeding mechanism and the pad depositing mechanism. These sprockets 185 and 186 are journaled in ablok 187 which slides be-' tween the guides 188 of the standard 189, and

is adapted for vertical adjustment by a hand wheel 190 which has a stem 191 journaled in an offset bearing 192 of the standard 189 and held against axial movement by engagement of the bearing 192 between the hub of the hand Wheel 190 and the collar 198 on the stem.

The lower end of this stem 191 is threaded and engages a threaded aperture in the block 187 so that by turning the hand wheel 190 the block 187 and sprockets 185 and 186 are raised and lowered. Idlers 194 are journaled on the standard 189 aboveiind at opposite sides of the sprocket 185 and have the upper length of the chain 17 4 passed therearound, as shown in Fig. 1, and similar idler sprockets 195 are mounted on the standard 189 at opposite sides of,and below the sprocket 186 to engage the lower length of the chain 174 in a similar manner. By this arrangement, it will be observed that when the hand wheel 190 is turned so as to raise the block 187 and the sprockets 185 and 186, the upper length of the chain 174 is shortened while the lower length is correspondingly taken up, and this results in a backing up of the cutter 160 so that the cutting operation is delayed, while operation of the hand wheel 190 in the reverse direction in a similar manner advances the operation of the cutter 160. Thus the point between the ends of the successive pads 108 at which the strip 24 is severed may be accurately regulated so that the loose ends 184 are of a uniform length.
